Abstract

See full text

An anode body for a solid electrolytic capacitor element, which is an anode body for a solid electrolytic capacitor element having a dielectric layer on the surface of a sintered body, wherein at least a part of the surface of the valve-acting metal particles constituting the sintered body is covered with a dielectric layer, and a part of the dielectric layer on the particle surface has a larger thickness than the other part; and a method for producing the same, in which a sintered body of a valve-acting metal is immersed in an aqueous solution of an oxidizing agent after being subjected to chemical formation, the resulting sintered body is then immersed in water-soluble alcohol and dried, and the oxidizing agent is removed by water washing.
